Differences in population parameters of Rattus norvegicus in urban and rural habitats of central Argentina
Life history characteristics are influenced by both biotic and abiotic factors of the environment. The aim of this study was to compare the life history strategies of Rattus norvegicus populations in urban and rural habitats in central-east Argentina. Live trapping of rodents was conducted over 1 ye...
